Nozzle is actually a simple solenoid valve, when the electromagnetic coil is energized, produce suction, needle being sucked on, open the nozzle, the fuel needle through needle head and the nozzle axis of the annular gap between the high-speed exhaust, the formation of mist, which will help complete combustion.

Nozzle plug will seriously affect vehicle performance. Blockage is due to coke deposition inside the engine or the fuel injectors on the fuel impurities such as blockage of the nozzle channel. Car running for some time, fuel systems will form some sediment.

The viscous material in the fuel injectors, intake valves and other parts of the combustion, the sediment becomes hard coke. In addition, due to urban traffic congestion, often in low speed and idling car state, but will increase the formation and accumulation of these sediments. Great harm fuel system deposits. Sediment can clog the 8N7005 nozzle of the needle valve, valve hole, affecting precision electronic injection system component performance, resulting in dynamic performance degradation. Sediment in the intake valve carbon deposit formation will result in the closure of lax and idle speed instability, the increase of fuel consumption and associated emissions deterioration. Sediments in the piston top and cylinder head and other parts of the formation of hard coke, coking of the heat capacity as high thermal conductivity is poor, prone to violent earthquakes and other engine failure. There will also be reduced by three per catalytic converter life.

The work of good or bad injector on each engine’s power plays a fundamental role. As the result of poor fuel injector, the cylinder coke serious. Cylinder, piston ring wear accelerated, resulting in unstable idle speed, fuel consumption, accelerate weakness, difficulty starting and emissions exceeded, will be completely blocked nozzle serious, causing damage to the engine. Therefore, regular cleaning DLLA138S1191 fuel injectors, for long periods of frequent cleaning or nozzle cleaning can cause a bad influence. As for the cleaning of the time, decide according to the vehicle speed, and usually increases the quality of the fuel.
